For the enhancement of many technical processes like reacting flows, mixing in chemical reactors or mixture formation in combustion engines the knowledge of spatial distribution of species is of great importance. The planar laser-induced fluorescence (PLIF) technique is a well established method to get 2-dimensional maps of concentration or mixture-ratio in a specific plane in the volume of interest. In our recent work we were able to validate a PLIF technique for the quantitative detection of fuel/air ratios (FARLIF) which will be used for mixture-formation investigations in optical engines [1, 2]. In many applications like mixture-formation in combustion engines not only the actual species or mixture distribution is of interest. The temporal evolution, the dynamics of the species distribution is often a key for the understanding and improvement of the fluid-dynamic processes.
